ROLLER SCREEN.

Application-med January 11, 1926. Serial No. 80,676..

Our invention is a roller screen for windows and the general object thereofis to provide a screen of this type which will be simple in construction, easy to assemble and install, economical, and eliicient in operation.

Other objects and advant-a'geswill appear hereinafter. v

The invention is illustrated inthe annexed drawing which forms a part of this specilication, and in which- Figure 1 is a transverse vertical section of a roller screen embodying our taken on line 1-1 of Figure 2. Figure 2 is a iront vertical section taken on line 2-2 of Figure 1`.

Figure 3 is a fragmentary horizontal section taken on line 3-3 of Figure 1.

Figure 4 is a modiied fragmentary transverse-vertical section with the -screen roll removed.

invention,

Corresponding reference characters desig-Y nate the same parts'in all the views.

In the -drawing 1 indicates a window frame including side stops 2, upper stop 3, side jamb members 4, and a jamb header 5.

ln the under side of the jamb header 5 we cut a longitudinalV vgroove 6 forwardly of within the groove 6 we place a roller mounting 8 and a' screen roller 9 which is mounted ing 8 may be formed of a sheet metal and comprises a Y zontal wall 10, end walls 11 bent upwardly from the ends of said bottom wall and back single piece of downwardly upon themselves, a, rear wall 12 bent upwardly from the rear edge of said bottom wall to about half the height of said end Walls, a horizontal flange 13 bent rearwardly from the upper'edge of said rear wall, and a flange 14 bent upwardly from the forward edge of said bottom Wall. The mountin 8 is placed with its end walls 10 against t e" 'de of the sidevjamb members 4, with its rear wall12 immediately in front of the upper sash 7 and with against the under side of the jamb header 5 above the sash. The outside members 15 of the end 'walls 11 extend below the bottom `wall' 10 -and screws 16 are driven throu h the lower ends of said members into the jamb members 4 whereby the mounting 8 is detachably mounted in the upper part of the window frame and within the 'groove' 6.

The inner members of the end walls Y10 in said mounting. The mountbottom hori.-

its anges 13.

are formed with offsets 17 provided with v square holes 18 to receive the square ends 19 of the shaft 2O of screen roller 9 whereby said shaft is held in the mounting 8 against turning. On 'the shaft 20 at the ends'thereof are journaled a pair of cylindrical wooden blocks 2l over which is fitted and to which is secured a' cylindrical roller tube 22, the

ends of which tube extending to the end walls,

10; and over the offsets 17. 'Aspring 23 is coiled around the shaft 20 and secured at one end to the sha'ft at 24 and at its other end in one of the blocks 21 at 25, which spring normally winds a screen 26 on the tube 22 of the roller, the upper end of the screen being secured to the tube at 27.

The lower end of the screen in a clamp 30 which consists of an outer clamp member 31 and inner clamp member 32.l The. outer member is offset inwardly at 33, while the inner member is bent inwardly upon itself at its upper edge at 34 and at its lower edge, at 35 which latter portion fits over Ythe outside of the lower portion of member 31 below theV offset 33. The lower end of the screen is held between the members 31 and 32 and is bent inwardly by the offset 33 under 'the upper bent portion 34 of the inf ner member 32 whereby the screen is held 26 is secured securely within the clamp so that it cannot pullY upwardly out of the same. rlhe clamp members 31 and 32 are securedltogether by wood screws 36 which extend outwardly through thesmembers 32 and 31' into a wooden strip 37, thus securing the strip and clamp to ther. The ends of the clamp 30 and the si e edges ofthe screen 26 extend into grooves-39 in the side-stops 2.

In the strip 37 are pivoted vertical spring catches 40 which extend through the strip and through catclrcasings 41 fitted in the strip, the catches being pivoted by pins 42 secured in said casings. Springs 43 are provided in said casings which urge the catches 40 into engaging position. The window sill 44 is provided with recesses 45 and slottcdcatch plates 46 provided with slots 47 are secured to the sill 44 by screws 48 with the slots 47 over the recesses 45.

When the screen 26 is drawn down o the roller 9 -the catches 40 extend through the catch plate slots 47 into the sill recesses 45 and engage the under side whereby .the screen is held down against the tension of the roller sprlg 23 over the front of the window. Upon easing the catches 40p-from the plates 46 the spring 23 winds the screen upon the roller.

' The modified form of the circular flange 13a disclosed in Figure 4 is integral with the rear straight wall 12 and is curved therefrom around the adjacent face of the groove V6 to .form a reinforcing housing to protect the screen roller 9 fromldamage and moisture,

should the jamb header 5. become broken or said rear wall resting in front of the window sash, said rear flange resting against the under side of the jamb head over said sash, and said end walls resting against the side jamb members of theV frame, means for securing the end wallsof the mounting` to the side jamb members, a roller mounted in said mounting, a screen securedand wound on said roller to be drawn down in front of the window frame, and means for holding the screen drawn down.' y

2. In a roller screen, a mounting comprising a bottom wall, a rear wall upstanding from the rear edge of said bottom wall, a

rear ange extending from the upper edge of said rear. wall, and end walls, said end walls being bent upwardly from the ends of said bottom wall and then downwardly upon themselves and the upwardly bent portlons being formed with oii'sets provided with fiatsided openings, the mounting being fitted in a groove cut in the under side of the window jamh header with the rear Wall 'of the mounting restingin front of the window sash, said rear flange resting against the under side of the jamb head over said sash, and said end-walls restin against the side jamb members of the wintgiow Jframe, means for securing the end walls of the mounting to the side jamb membersa rollerconstructed with a shaft with flat-sided ends adapted to fit in said fiat-sided openings in said oil"- sets, a screen secured and wound on said roller to be drawn down in front of the window frame, and means for holding the screen drawn down.

3. In a roller screena mounting comprising a bottom wall, a rear wall upstanding from thefrear ed e of said bottom wall a rear flange exten ing from the upper edge of said rear wall, and end walls, said end Walls being bent upwardly from the ends of said bottom wall and then downwardly upon themselves below said bottom wall, the lower ends of the downwardly bent portions of said end walls being provided with screw holes to receive screws for securing the end walls to the side jamb members with the mounting fitting in a groove cut in the under side of the window jamb header, with said rear wall resting in front of the window sash and with said rear'iiange resting against the under 'side of the jamb head over said sash, a roller mounted in said mounting, a screen secured and wound on said roller to be drawnv down in front of the window frame, and means'ifpor holding the screen drawn down.
